Payroll true-up reports

BWC determines employer premiums based on the amount of payroll (exposure) reported multiplied by a specific rate. At the beginning of each policy period, we’ll set an estimated annual premium (EAP) as follows.

For a new employer, we'll establish your estimated annual premium by using the 12-month payroll estimate you submitted on your application for workers' compensation coverage.

For an existing employer that had coverage before this policy period, we’ll establish your estimated annual premium by using the most recently reported payroll.

At the end of the policy year, we must ensure the estimated premium we set for you was correct. To do this, you must
file a true-up report that reflects the actual payroll for that policy year. You must complete the report online usingthe
Payroll true-up report service offering.
